Fix mapping and bulk URL for ES 8.X and OS 2.X

[Rafaeltheraven]

The way support for ES 7.X and OS 1.X was originally implemented meant that any major version that was not EXACTLY 7/1 would revert to old behavior. This is obviously wrong and simply changing this check to allow versions >= 7/1 seems to just work (at least in the context of using mordred to import git data from perceval).

I can not guarantee that everything works, and I know that at least kibash still needs some work as discussed here. But in any case, the check was wrong, and this PR should at least fix that.

:edit: Recreated this PR as I messed up what branch I used as the source for this PR and the old one got unclean.

Thanks for your patch. Could you rebase the PR (cause the tests are failing) and squash the commits?

I also see some unrelated code to the PR inside the .github/workflows directory.

Thank you

My apologies, the project for which these fixes were originally made ended so I got distracted, I've cleaned up the PR now and squashed everything into 1 commit.
